Turn on a Mac mini, Mac Studio or iMac without pressing its power button
You can configure some desktop Mac computers to turn on automatically when connected to a power source. This feature can be helpful when you don’t have easy access to the computer’s power button.
System requirements
This feature requires macOS Tahoe 26.5 or later and one of these computers:
Mac mini introduced in 2024 or later
Mac Studio introduced in 2025 or later
iMac introduced in 2024 or later
Set your Mac to start up when a power source is connected
From the Apple menu , choose System Settings.
Click Energy in the sidebar.
From the “Start up when power is connected” menu on the right, choose Always. This setting is only available on computers that meet the system requirements.
Your Mac will now turn on automatically whenever you connect it to a power source, such as when plugging it into a power socket or restoring power using an external power switch. It will also turn on automatically when power is restored after a power failure.
If your Mac has remained connected to a power source since it was shut down, it’s best to wait about 30 seconds between disconnecting and reconnecting power to turn on your Mac. This gives your Mac power supply time to discharge.
